It is west of downtown in the LeBreton Flats area, near the new Canadian War Museum.
The building was opened in 1875 as Ottawa's first pumping station (PS) and pumped unfiltered water from the Ottawa River into the city's new water distribution system.
These two plants produce 275 million litres of water every day.
The Fleet Street PS still plays an important role in the city's water distribution system.
The discharge from the PS provides a class 2 whitewater site used by canoe and kayak enthusiasts.
